Let's look at real world speaker design. In my set up, as well as most of yours a horizontal center is the only option. I happen to have a very large (70") tv. So a vertical center under it is not workable, and putting one on top of it would make it
7 feet tall!!
Anytime somebody comes out with a new speaker/sub/cd player/amp, there is going to be chatter about how good/bad it is. The good news is that most of the players are trying to build a better product. Thats how competition works.
The beauty of a company like SVS (and others) is that their product is available to a much larger market than some others. I live in a small town. I would have to drive at least 100 miles to hear anything decent at all.
The bad news is that in a market as old as speakers, the odds of a truly revolutionary product are slim. We can hope for a product as good as others, but for less money. That's about it.
I will be more interested in the larger models. I hope they go over the top on those!
